Where In Ottawa XLV

Traditionally, my Where In Ottawa photo challenge runs on the first Monday of each month, but with the passing of Leonard Nimoy, I couldn't let time elapse without honouring the iconic man.

But it's back, and I'm hoping that this time the challenge isn't solved as quickly as it has been in the past two months.

If you haven't played this challenge before—or even if you have but you've forgotten the rules—here are the conditions of play.

• The following photograph was taken somewhere in the greater Ottawa region. Your job: locate it.
• If you think you know the location of the structure in the image, leave your guess in the Comments section of this post. Answers sent to me by Twitter, Facebook, e-mail, or any other method than by writing a guess in the Comments section do not qualify for this challenge. I will not reply to any other form of guess.
• If you were with me when I took the photo, you may not participate in the challenge.
• If you have won Where In Ottawa in the past, you may still participate; however, if you guess correctly, no giveaway will be awarded.
• The first person to correctly identify the location of the structure in the photograph will receive a PDF copy of my novel, Songsaengnim: A Korea Diary.
• You may leave as many guesses as you want.
• Starting tomorrow, I will leave clues to the location in the upper-right column of this post, adding a new clue each day until the challenge is solved.
• If the challenge has not been solved by noon, Ottawa time, on Sunday, March 15, the challenge will end and I will reveal the location on Monday, March 16.
• The winner of Where In Ottawa has until the end of Sunday, April 5, to claim his or her giveaway.

That's basically it. So are you ready? Here is this month's photo:

Think you know Ottawa? Prove it!

And good luck!
